Across all of North America, the National Simplex Frequency (also referred to as the calling frequency) is 146.52 MHz. In areas that use 15-kHz channels, the adjacent channels are 146.535, 146.550, 146.565 MHz, etc. moving upward. Below the calling frequency are 146.505, 146.490, 146.475 MHz and on.
Who must be in physical control of the station apparatus of an amateur station aboard any vessel or craft that is documented or registered in the United States?Specifically, the control operator (the person in physical control of the station apparatus) must either hold a valid FCC-issued amateur radio license or they must be authorized for alien reciprocal operation — that is, they can operate if they are an alien (non-US citizen) holding a license in a country with whom the …
Article first time published onHow Much Power Should I run on FT8?
You should always try to use the minimum power required to make a QSO. In weak signal modes such as FT8, people usually run up to 25–30 Watts. Keep in mind that the duty cycle is 100% and prolonged high power transmission will lead to overheating and could harm the radio. Personally, in FT8 I use about 15 Watts.
What do I need for FT8?
- An HF transceiver with data or SSB capability.
- An audio interface, a way to get receive audio from the radio into a computer and audio output of the computer into the radio, typically a sound card interface.
- A computer capable of running the FT8 software and time synchronization.
What is the difference between FT8 and FT4?
Introduction: FT4 is an experimental digital mode designed specifically for radio contesting. … T/R sequences are 6 seconds long, so FT4 is 2.5 × faster than FT8 and about the same speed as RTTY for radio contesting. FT4 can work with signals 10 dB weaker than needed for RTTY, while using much less bandwidth.
How long is a 10 meter dipole antenna?
A 10 meter dipole would be around 16 ft.
What is the maximum symbol rate permitted for RTTY?
The maximum symbol rate permitted for RTTY or data at frequencies below 28 MHz is 300 baud.
How long is a 60 meter dipole?
Total length approximately 26.6 meters.

What frequencies do railroads use?
Most railroads use a set of 97 frequencies between 160 and 162 MHz. Most operations are in “Conventional/Analog” mode, that means they do not usually use trunking, digital or other complicated modes. Most railfans will want to have a handheld scanner that you can use while standing line side.
How far can a SSB radio transmit?
SSB (Single Sideband) radio has a much greater range than a VHF (Very High Frequency) radio’s typical 35 to 50 nautical miles. Medium Frequency (MF) SSB radio has a range of around 400 nautical miles, but High Frequency (HF) will reach out for several thousand.
Is 10m USB or LSB?
NOTE: The “standard” and internationally used and accepted mode on 10 meters is USB, NOT LSB. Please refrain from using LSB ON 10 METERS! When you upgrade to the General or the Extra license class, similar rules apply to your band edges. On 160, 75/80, and 40 meters, use LSB.
Is SSB FM or AM?
Without going too deep into the technical stuff, you may be interested to know that SSB actually came from the AM mode. It is about 1/4 of the AM signal (one of the TWO side-bands that make up an AM transmission), minus the “carrier” (the raw radio signal that “carries” the voice or other modulation).
How far can you talk on 2 meters?
On VHF frequencies such as 2-meters, antenna height greatly influences how far one can talk. Typical reliable repeater range is about 25 miles (40 km). Some repeaters in unusually high locations, such as skyscrapers or mountain tops, can be usable as far out as 75 miles (121 km).
What is the 2 meter calling frequency?
2 Meters (144-148 MHz)
What is the national 10 meter FM calling frequency?
28.400mhz voice band center and used as the “calling” frequency.
What are kdr444 frequencies?

- Coast radio station.
- Marine VHF radio.
- Maritime mobile amateur radio.
What are the GMRS frequencies?
The General Mobile Radio Service (GMRS) is a licensed radio service that uses channels around 462 MHz and 467 MHz. The most common use of GMRS channels is for short-distance, two-way voice communications using hand-held radios, mobile radios and repeater systems.

What is the maximum power permitted on the 2200 meter band?
2) Only General and above licensees may transmit on 630 meters and 2,200 meters. 3) On 2,200 meters, the maximum Equivalent Isotropically Radiated Power (EIRP) is 1 watt with a maximum transmitter Peak Envelope Power of 1,500 watts allowed.
What are the FCC rules regarding the use of a phonetic alphabet for station identification in the Amateur Radio Service?
What are the FCC rules regarding the use of a phonetic alphabet for station identification in the Amateur Radio Service? Using a phonetic alphabet (also called a “spelling alphabet”) such as the NATO Phonetic Alphabet is encouraged by the FCC rules but not absolutely required.
How does FT8 mode work?
With FT8, you’re restricted to very small messages, with a limit of 13 characters per message. Each message of up to 13 characters takes 13 seconds to send. There are 4 slots per minute, and you transmit for one 15 second block, then listen for replies for 15 seconds, and transmit again for 15 seconds.
What does FT8 stand for?
FT8 stands for “Franke-Taylor design, 8-FSK modulation” and was created by Joe Taylor, K1JT and Steve Franke, K9AN. It is described as being designed for “multi-hop Es where signals may be weak and fading, openings may be short, and you want fast completion of reliable, confirmable QSO’s”.
